Kalanchoe plant named ‘Fikalrudak’

ABSTRACT

A new and distinct cultivar of  Kalanchoe  plant named ‘Fikalrudak’, characterized by its compact, upright and uniformly mounded plant habit; moderately vigorous growth habit; freely branching plant habit; glossy dark green-colored leaves; uniform, early and freely flowering habit; bright pink-colored flowers; and excellent postproduction longevity.

Botanical designation: Kalanchoe blossfeldiana.

Cultivar denomination: ‘FIKALRUDAK’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Kalanchoe plant,botanically known as Kalanchoe blossfeldiana and hereinafter referred toby the name ‘Fikalrudak’.

The new Kalanchoe is a product of a planned breeding program conductedby the Inventor in De Lier, The Netherlands. The objective of thebreeding program is to create new freely-branching and freely-floweringKalanchoe plants with attractive leaf and flower coloration.

The new Kalanchoe plant originated from a cross-pollination made by theInventor in De Lier, The Netherlands in 2011 of Kalanchoe blossfeldiana‘Kerinci’, disclosed in U.S. Plant Pat. No. 10,031, as the female, orseed, parent with Kalanchoe blossfeldiana ‘Aniak’, disclosed in U.S.Plant Pat. No. 18,742, as the male, or pollen, parent. The new Kalanchoeplant was discovered and selected by the Inventor as a single floweringplant from within the progeny of the stated cross-pollination in acontrolled environment in De Lier, The Netherlands in December, 2012.

Asexual reproduction of the new Kalanchoe plant by vegetative terminalcuttings in a controlled environment in De Lier, The Netherlands since2013 has shown that the unique features of this new Kalanchoe plant arestable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Kalanchoe have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature, daylength and light intensity without, however, anyvariance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Fikalrudak’. These characteristics incombination distinguish ‘Fikalrudak’ as a new and distinct Kalanchoeplant:

-   -   1. Compact, upright and uniformly mounded plant habit.    -   2. Moderately vigorous growth habit.    -   3. Freely branching plant habit.    -   4. Glossy dark green-colored leaves.    -   5. Uniform, early and freely flowering habit.    -   6. Bright pink-colored flowers.    -   7. Excellent postproduction longevity.

Plants of the new Kalanchoe can be compared to plants of the femaleparent, ‘Kerinci’. Plants of the new Kalanchoe differ from plants. of‘Kerinci’ in the following characteristics:

-   -   1. Plants of the new Kalanchoe are more compact than plants of        ‘Kerinci’.    -   2. Plants of the new Kalanchoe flower about three to four days        later than plants of ‘Kerinci’.    -   3. Plants of the new Kalanchoe have larger flowers than plants        of ‘Kerinci’.    -   4. Plants of the new Kalanchoe and ‘Kerinci’ differ in flower        color as plants of ‘Kerinci’ have dull pink-colored flowers.

Plants of the new Kalanchoe can be compared to plants of the maleparent, ‘Aniak’. Plants of the new Kalanchoe differ from plants of‘Aniak’ in the following characteristics:

-   -   1. Plants of the new Kalanchoe are more vigorous than plants of        ‘Aniak’.    -   2. Plants of the new Kalanchoe have slightly smaller flowers        than plants of ‘Aniak’.    -   3. Plants of the new Kalanchoe and ‘Aniak’ differ in flower        color as plants of ‘Aniak’ have darker pink-colored flowers.

Plants of the new Kalanchoe can be compared to plants of the Kalanchoeblossfeldiana ‘Oriba’, disclosed in U.S. Plant Pat. No. 13,337. Inside-by-side comparisons conducted in De Lier, The Netherlands, plantsof the new Kalanchoe differed from plants of ‘Oriba’ in the followingcharacteristics:

-   -   1. Plants of the new Kalanchoe were more compact than plants of        ‘Oriba’.    -   2. Plants of the new Kalanchoe flowered about three to four days        later than plants of ‘Oriba’.    -   3. Plants of the new Kalanchoe had larger flowers than plants of        ‘Oriba’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurementsand values describe plants grown during the summer and autumn in 10-cmcontainers in a glass-covered greenhouse in De Lier, The Netherlands andunder cultural practices typical of commercial Kalanchoe production.During the production of the plants, day temperatures ranged from 20° C.to 25° C., night temperatures ranged from 20° C. to 21° C. and lightlevels ranged from 10,000 lux to 55,000 lux. Plants received longday/short night conditions (more than 14 hours of light) for about fourweeks then plants received photoinductive short day/long nightconditions (minimum 14 hours darkness) until flowering. Plants weretwelve weeks old when the photograph was taken and eleven weeks old whenthe description was taken. In the detailed description, color referencesare made to The Royal Horticultural Society Colour Chart, 2007 Edition,except where general terms of ordinary dictionary significance are used.
